MULTIPLIER 0F EFFICIENCY FOR FLOAT APPARATUS.

Specification of Letters Patent.

Patented Oct. in, 1915.

Application filed September 12, 1913. Serial No. 789,575.

To all whom it may concern.

Be it known that I, OTTO RosoHANEK, engineer, citizen of Austria, residing at Vienna, Lower Austria, Austria-Hungary, have invented certain new and useful Improvements in Multipliers of Efliciency for Float Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to the disposal of water of condensation in steam lines, and has special reference to an appliance adapted for attachment to a steam trap to increase the efliciency thereof.

The principal object of the invention is to provide an appliance which will increase the effective capacity of a steam trap so as to render the number of operations of the trap less while at the same time maintaining complete discharge of the water from the steam line.

Another object of the invention is to provide means whereby oil, carried over with the steam, may be separated prior to reaching the trap, the oil being collected in the appliance forming the subject matter of this invention and arrangement being made to draw ofi said oil from time to time.

A third object of the invention is to prevent the formation of a vacuum in the appliance and to permit the discharge of cold air therefrom prior to the operation of the appliance.

lVith the above and other objects in view the invention consists in general of certain novel details of construction and combination of parts hereinafter fully described. illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several. views, and Figure 1 is a detail section showing the preferred form of the device. Figs. 2 to 11 are various modifications of this form. Figs 12 and 13 are other modifications employing a tubular structure. Fig. 1 1 is a sectional view of a modification of Fig. 4 shown in connection with a steam trap, a bypass being employed between the two for purposes hereinafter to be described. Figs. 15 to 17 are modifications of the valve arrangement shown at the top 01 Fig. 1.

In the various modifications shown in Figs. 1 to 11 and also in Fig. 14 the appliance is provided with a body 1 having an inlet 2 and an outlet 3. Depending into the body 1 in each of these forms is a portion, tubular or otherwise, providing an escape passage l which communicates with the outlet 3 and communicating with this escape passage from the interior of the body 1 is a bleeder 5. In the form shown in Fig. 1 there is provided, intermediate the ends of this bleeder 5, a valve 6 which is controlled by a handle 7 so that the valve may be opened or closed to any desired degree.

In the form shown in Figs. 3, 4t, 6, 7, 8, 9 and 14:, the bleeder opens directly into the outlet passage I and is similarly equipped with the valve 6 and operating handle 7.

In the forms shown in Figs; 2, 5, 10 and 11, the bleeder opens directly into the outlet passage but is not provided with a valve, the bleeder being regulated in size for the purpose desired during the process of manufacture.

As shown in Fig. 1 a suitable water gage 8 may be provided and as indicated in Figs. 1, 3 and 1 substantially vertical bafl'les 9 may also be provided. Furthermore horizontal baflles 10 may be disposed below the inlet ends of the passage 1 as indicated in Figs. 1, 1, 5, 8, 10, 11 and 14. In certain forms, as in Figs. 1 and 4 both the vertical and horizontal battles are employed.

In the form shown in Fig. 5 a second bleeder 5 afiords communication from the interior of the body 1 to the passage 41 below the bleeder 5 and this bleeder 5' is controlled by a valve 16 actuated by a handle 7.

In the form shown in Fig. 6 the mouth of the passage 1- is adapted to be controlled by a valve 17 operated by means of a handle 17. The same arrangement is .used in the modification shown in Fig. 7 but surrounding the lower end of the passage 4L is a cup shaped bafi'le 18.

In the modification illustrated in Fig. 8 the inlet passage 2 is provided, like the outlet passage, with a downwardly extending passage 1 having a battle 10 at the bottom and in the upper part of this passage there is I pipe extending upward into the hood and communicating with the escape or outlet opening 3. In each of these forms the hood 19 is provided with the bleeder but in Fig. 9, as previously noted, the bleeder is controlled by the valve.

In Fig. 10 an annular baffle 10 is arrz nged below the hood 19, thus acting in the same manner as the baffle 10.

The form shown in Fig. 11 is especially adapted for insertion, in steam lines intermediate the ends of said lines, an outflow or exhaust pipe 21 being provided so that while the outlet 3 may be connected to a steam trap,the dry steam in the upper part of the casing 1 may escape through the passage 21.

' In the form shown in Fig. 14 a bypass 24k is provided between the casing 1 and a steam trap #22 of the usual type, the bypass being controlled by a valve 23 and the steam pipe being provided with a manually operable valve 26 so that when desired, by proper manipulation of these valves, the steam trap may be blown out.

In the forms shown in Figs. 12 and 13 the casing 1 is replaced by a U-shaped pipe 1 having the inlet end 2* and outlet end 3. This outlet end is connected to the usual steam trap T as previously described and between the upper ends. of the pipe 1, bridging the same, is a bleeder pipe 5 which is controlled. by a valve 6?, thus taking the place of the bleeder opening 5 and valve 6.

The form shown'in Fig. 13 modifies the form shown in Fig. 12'slightly by being pro vided with a chamber 1 into which extends a downwardly projecting end 1 of the outlet branch of the tube 1.

In each of the forms just described the arrangement of the bleeder, which it is to be noted opens in all instances directly into the outlet pipe, is such that the major portion of the water of condensation collects in the easing 1 while at the same time a certain portion of the steam passes over into the steam trap there to operate the float, the device being intended to work in connection with a float trap, so that at the same time that the float is operated to open the valves of the trap the water level in the casing 1 will have risen to such height as to be ready to overflow into said trap. Now, as soon as the escape valve from the trap is opened a reduction of pressure takes place in the outlet 3 and the size of the bleeder is so regulated, either during manufacture, or by means of the valves described in connection therewith, that the pressure in the upper part of the casing 1 remains less than the pressure in the escape passage and the trap during the operation of the device, the opening being of such size as to prevent equalizingof said pressure. Fhiscauses the steam pressure on the body of water within the appliance to force said water over into the trap until the lower end of the passage t has been exposed to the action of said steam pressure. Thus, not only is the water contained in the trap exhausted through the trap exhaust 20 but also the water, or the greater portion thereof, contained in the attachment or appliance is likewise exhausted. Thus the valves in the trap do not have to operate as often as where the device works without the appliance while the appliance itself has no moving valve which operates during the discharge of water. This of course increases the eiliciency and lengthens the life of the trap so that a smaller trap can be used with as great elliciency.

By regulating either the size of the bleeder opening or its valve it will be obvious that the pressure in the inlet passage 2 and the pressure in the outlet passage 3 may be equalized after any desired quantity of the contents of the casing 1 has been discharged so that allowance may be made for the collection of the oil on top of the water in the casing 1, the remainder of the water and the oil thereon being drawn off through a suitable opening 11 as shown in Fig. 1, the opening being of course provided with a usual valve. Moreover the arrangement of the baffles prevent both the lighter floating particles of solid matter and the heavier mud from passing over into the trap and thus prevents injury of the trap valves by this accumulation of this solid matter.

In the form shown in Fig. the lower bleeder 5' may also be used to assist in the discharge of the water while in the forms shown in Figs. 6 and 7 the valve 17 may be used to assist in the balancing of the opening of the passage -l and the bleeder opening 5 that is necessary for effective operation of the device. In the upper part of any one of these devices there may be provided anair escape or release valve. In the form shown in Fig. 1 this air escape or release valve comprises a valve body 27 fitted in a suitable opening in the top of the casing 1 and provided with a hood having openings 29 in the sides thereof. Slidably mounted in the hood 28 is a valve stem 30 which carries an inwardly opening valve 31 arranged to seat against a suit able seat provided in the body 27. Mount ed on the stem 30 is a stop nut surrounded by a flange 35 and surrounding the stem 30 between the stop nut and the top of the hood is a coil spring 3% which normally holds the Valve 31 open, the open movement of said valve being controlled by the nut 36 of the outer end of the stem. Thus so long as there is no pressure in the upper part of the casing 1 the valve will remain open and the air can escape. When however pressure comes in the upper part of said casing the valve 31 closes and the device is then ready for operation. In Fig. 15 there is shown a modification of this valve structure wherein there is provided a ball valve 31 which takes the place of the valve 31 and is provided with a stem 30 This stem 30 passes up through a ball valve 37 having a double conical opening 33 there through for the reception of said stem. The stem moreover is provided with suitable tappets 30 at each side of the ball 37 so as to limit the movement of the stem in the ball. Thereby the ball 37 is raised off the scat before the ball 31 seats upon the seat so as to provide time for the escape of air. Figs. 16 and 17 show further modifications of this valve wherein there is provided a valve casing 37 consisting of upper and lower halves between which is secured a diaphragm 38 having port openings 11 therein. This diaphragm 38 in each instance supports a valve 31 which is arranged to close an opening 41 in the upper part of the valve casing.

In the form shown in Fig. 16 the valve 31 is normally held open by means of a ball 39 carried on a lever 39 and having pivotal connection to a rod 39 which extends down into the valve stem 33, the latter being hollow. In the form shown in Fig. 17 the upper part of the valve. casing 27 is provided with a hood 28 and opening 29 so that the spring 34 may be held to bear against a hollow valve stem 40 connected to the valve 31 thus normally keeping said valve open. In these last two forms the device is practically frictionless.
